CVE-2026-15665: CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in wpmanageninja Fluent Support – Helpdesk & Customer Support Ticket System
The Fluent Support – Helpdesk & Customer Support Ticket System plugin for WordPress is vulnerable to Stored Cross-Site Scripting via 'redirect-to' Shortcode Attribute in all versions up to, and including, 2.3.0 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The XSS payload is in a hidden attribute so it only fires in specific browsers when specific access keys are used making exploitation unlikely.
AI Analysis
Technical Summary
CVE-2026-15665 is a stored cross-site scripting vulnerability in the Fluent Support WordPress plugin (up to version 2.3.0). It results from improper neutralization of input in the 'redirect-to' shortcode attribute, enabling authenticated contributors or higher to inject arbitrary web scripts. The vulnerability's exploitation requires specific browser conditions and access keys due to the payload being in a hidden attribute, reducing the likelihood of successful attacks.
Potential Impact
An authenticated attacker with contributor-level or higher privileges can inject persistent malicious scripts into pages via the vulnerable shortcode attribute. This can lead to limited confidentiality and integrity impacts, such as executing arbitrary scripts in the context of users viewing the injected page. However, the exploitability is reduced due to the payload being hidden and triggered only under specific conditions. There is no impact on availability.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict contributor-level access to trusted users and monitor for suspicious shortcode usage. Avoid using the vulnerable shortcode attribute if possible.
